The success of the first set of cement rotary kiln oxygen-rich combustion technology transformation project in Shandong Juzhou Cement 5000t/d clinker production line, CAI Hui has a deeper understanding of how oxygen-rich combustion technology can better serve the energy saving and consumption reduction of the cement industry. "We have realized before the project started that the application of oxygen-rich combustion in cement production line is a systematic project, so we have done a lot of work from the early preparation and later implementation, which is why the project name is called the oxygen-rich combustion technology transformation project rather than the oxygen-rich combustion technology application project, we do not only install the oxygen-rich device, The production line is also dynamically matched and optimized." CAI Hui said in an interview with China Cement network. For a long time, in order to seek technical breakthroughs, Hangzhou Teyin and Southwest University of Science and Technology, Zhejiang University, China Coal University, Germany Humboldt, Germany Schenker, Xi 'an Fister and other related industry enterprises and experts work together, jointly committed to the dynamic matching technology of oxygen-rich combustion process, to achieve energy saving and emission reduction of industrial kilns and industrial boilers. The technical reform project of oxy-enriched combustion process of cement rotary kiln was strongly supported by Southwest University of Science and Technology. Before the implementation of oxy-enriched combustion process transformation, the thermal calibration of the firing system of the production line was carried out, and the range of thermal calibration was analyzed and diagnosed: C1 outlet to the clinker cooler outlet (including the wind for raw material grinding and waste heat power generation heat exchange). During the measurement period, the sintering system ran smoothly, and most of the data collected were within the normal fluctuation range.
